When I bought my 37, it was set up with a lefty safety too. Buy the right handed safety, watch a youtube video and the swap is very simple. Sell the lefty safety on here or on eBay. I also changed out the Raybar front site for a large brass bead, opened the choke waaay up, and cut and refinished the stock into an English style grip. It's now an upland woodcock, grouse and bunny slayer. Oh and it's a 16.
